In this paper, a reduced-order finite element method (FEM), which is based on proper orthogonal decomposition (POD) technique, is applied to the time fractional Tricomi-type equation.The presented method is an improvement on general FEM and can alleviate the computational load and memory requirement effectively due to its reconstruction of POD basis functions.Furthermore, the reduced-order FEM is proved to be unconditionally stable and the error estimates are derived in detail.Numerical examples are presented to illustrate the feasibility and effectiveness of the method for time fractional differential equations.
